1. Project background
At present, places like hotels, amusement parks, large factories, hospitals and other places have a large number of uniforms that need to be processed every morning at work. Employees need to queue to the clothing room to pick up uniforms, just like going to a supermarket to shop and check out. Later, they must be registered and returned one by one. Sometimes there are dozens of people in line, and it takes a few minutes for each person. Moreover, the current management of uniforms basically uses manual registration, which is not only very inefficient, but also often leads to errors and loss.
The uniforms sent to the laundry factory need to be handed over to the laundry factory every day. The staff in the uniform management room hand over the dirty uniforms to the laundry factory staff. After the two parties carry out the classification and counting of the uniforms, the two parties sign for approval. When the laundry factory returns the clean uniforms, the laundry factory staff and the uniform management office staff will check the type and quantity of the clean uniforms one by one, and both parties sign after verification. Every 300 uniforms require about 1 hour of handover time per day. During the handover process, the laundry quality cannot be checked, and it is impossible to talk about how to improve the laundry quality to increase the life of the uniform and how to effectively reduce the inventory and other scientific and modern uniform management. Especially as people’s awareness of disease prevention and treatment continues to increase, it is a very arduous task to count the number of medical suits when they are handed over.
For high-end hotels, hospitals and other units with high hygiene requirements, employees need to change and wash their work clothes regularly, and employees who do not change regularly need to be urged. The current manual management method cannot monitor whether employees are regularly changed and washed, and it cannot be scientifically based on employees’ attendance. Dynamically adjust the frequency of changing and washing employee uniforms.
The use of uniforms to commit crimes is constantly increasing. How to ensure that the uniforms of the unit are not used by people with bad intentions after they are lost. It has also become a very important issue for many enterprises and institutions.
UHF electronic tags have been widely used in various industries due to their characteristics that they can be read in large quantities at a time from a long distance. However, because the electronic tag is composed of electronic circuits, its easy to fold, non-waterproof and other characteristics hinder its popularization and application in the field of uniform management.
Based on this, Fujitsu has developed a water-resistant, heat-resistant, pressure-resistant, and alkali-resistant UHF band RFID tag WT-A511, which allows RFID technology to be applied to uniform management. And the reusable feature of the label greatly improves her cost-effectiveness, and reduces the average cost per use of the label very low. At present, many hotels, hospitals, and amusement parks in the world have adopted this label to manage their uniforms, which not only effectively improves the efficiency of uniform management, but also greatly reduces the labor cost of uniform management. In China, the label has been widely used in hospital gowns and bed sheets and quilt management systems in hospitals.
2. System composition
The system consists of the following parts:
Electronic label: Fujitsu’s washable label WT-A511
Read and write device: a reader that complies with EPC global C1G2 standard
Server: used for background data collection and processing
Software: uniform management software, database software
The basic workflow of the system:
Through the label management system, uniform collection, logistics and acceptance can be completed instantly and accurately, which can greatly improve the efficiency of uniform management. Using the tag tracking management system, relevant personnel can confirm the location of each set of uniforms, the number of times they have been washed and other information at any time. The system can automatically prompt the disposal information of the uniform when the uniform reaches a certain state according to the prior settings.
Regarding changes in uniform status:
1. Initialization state
2. When adding a new uniform to the system, you can specify the state of the uniform. Generally, the state of the uniform at this time should be designated as “Pending Loan”.
3. The timing of the status change to “Lending”. When the employee lends out the uniform, he will perform the lending operation at the uniform handover window. At this time, the uniform status will be changed to “Lending”.
4. The time when the status changes to “to be washed”. When the employee returns the uniform, he will perform the return operation at the uniform handover window. At this time, the uniform status will be changed to “to be washed”.
5. The time when the status changes to “send for washing”. When the uniform is handed over to the laundry service provider (the laundry service provider removes the uniform), the uniform delivery operation must be performed at the uniform handover window. When the delivery is confirmed, the status of the uniform will be changed to “delivery for washing”.
6. The time when the status changes to “to be borrowed”. When the uniform is handed over to the laundry service provider (the laundry service provider returns the uniform), the storage operation must be performed at the uniform handover window. When the storage is confirmed, the status of the uniform will be changed to “pending loan”.
7. The time when the status changes to “lost”. The uniform manager discovered that the uniform was lost. In one case, the employee reported the loss, and in the other case, the laundry service provider reported the loss. According to the corresponding regulations of the enterprise management process, after confirming that the uniform is lost, the uniform administrator can modify the uniform status to “lost” through the uniform information update screen of this system.
8. The timing of the status change to “scrap”. When the uniform manager finds that the uniform is worn or damaged, he confirms that the uniform is unusable according to the corresponding regulations of the enterprise management process. The uniform manager can update the uniform status through the uniform information update screen of this system to change the uniform status to “scrap”.
3. Implementation in a hotel
The uniform management of a hotel has always been manual registration, and uniforms are distributed to hundreds of employees every day. Every morning when I go to work, I have to line up to pick up uniforms in the clothing room. Sometimes there are dozens of people in line, and it takes 3 minutes for each person. It’s like going to a supermarket to check out. You need to register and borrow them manually. In order to improve production efficiency, the hotel introduced Fujitsu washable labels to manage uniforms. The hotel puts a label on each uniform and automatically uploads the data to the server through the chip. When a set of uniforms is checked by the reader, it is instantaneous. Read the model, size, color and other information of all clothes without having to scan barcodes one by one as before. In addition, due to the use of labels for clothing management, the hotel has also adopted a clothing self-service system to improve efficiency. The hotel sets up the self-service system outside the clothing room. After the employees receive the clothing, they only need to go to the equipment, swipe the employee card, and then put a few uniforms in front of the reader to quickly confirm the loan. The system It greatly saves the time for employees to lend out uniforms. At the same time, if an employee takes the wrong uniform, the system can also automatically remind the employee based on the clothing style and size recorded in the employee card. After adopting this system, the system has improved the efficiency by more than 50%.
RFID is applied to clothing self-service system, which not only has high reading accuracy and fast speed, but also can read the information of multiple pieces of clothing at the same time. Compared with the previous clothing management technology, RFID operation is simple and efficient.
From a technical point of view, taking into account the labeling of clothing, it is necessary to ensure the comfort of employees and not be too obvious to be seen by guests. In the design of this washable label, Fujitsu uses special materials to encapsulate, making the label soft and compact. It is heat-resistant and washable, and can be used for washing and ironing hundreds of times. Compared with the barcode management used in many industries, Fujitsu’s technology can scan 50, 100, or even 200 pieces of clothing at a time, instead of manually scanning one piece at a time. Thereby greatly improving management efficiency.
At present, in addition to being widely used in various clothing management industries such as hospital uniform management, hotel uniform management, uniform rental management, dress rental management, etc., the label will also be promoted and applied in clothing washing and dyeing industries.
4. Project features:
1. Because the interface of this label adopts the EPC global C1G2 specification, and this specification has been widely popularized and applied as a de facto global standard. Therefore, its versatility allows users to use existing read-write devices to read and write the tag without having to repurchase a dedicated read-write device. So as to help customers maximize the control equipment investment.
2. Since the reader can read hundreds of tags at a time, and can read the tags across the package, the packaged uniform can be read through the reader without opening the tag information, so the uniform handover process is greatly improved Improve work efficiency. The handover work that used to take several hours can be shortened to a few minutes.
3. It can count and query the washing times of each uniform, arrange reasonable recycling time, and arrange orders in a timely and reasonable manner, so as to achieve efficient management of inventory and uniform life cycle.
4. The department and staff information of each uniform can be inquired. This function can be effectively used to prevent theft of uniforms and improve the awareness of employees to keep personal uniforms.
5. The processing speed is fast, accurate and safe. Improve the efficiency of uniform distribution, collection, and collection management, increase the efficiency of inventory, storage and exit management, and reduce human errors that are likely to occur during manual management.
